\(यदि (U={1,2,\ldots,36}), (A={x:x\) 4 का गुणज है\(}) और (B={x:x\) पूर्ण वर्ग है\(}), तो (A'\cap B') में कौन सा अवयव होगा\)?
\(If (U={1,2,\ldots,36}), (A={x:x\) is a multiple of \(4}) and (B={x:x\) is a perfect square\(}), which element belongs to (A'\cap B')\)?

Correct Answer
A. (18)
Concept
\(A'\cap B'\) contains elements that are neither multiples of (4) nor perfect squares. (18) is in neither of them.
Why this answer is correct
The correct answer is A. (18). \(A'\cap B'\) contains elements that are neither multiples of (4) nor perfect squares. (18) is in neither of them.
Exam Tip
\(A'\cap B'\) में वे अवयव हैं जो न (4) के गुणज हैं और न पूर्ण वर्ग हैं। (18) इन दोनों में नहीं आता।
